option 4-way-handshake resend
Use option 4-way-handshake resend to set the maximum number of retransmissions for an EAPOL-Key packet and the retransmission interval.
Use undo option 4-way-handshake resend to restore the default.
Syntax
option 4-way-handshake resend max-count [ interval interval ]
undo option 4-way-handshake resend
Default
The maximum number of retransmissions for an EAPOL-Key packet is three, and the retransmission interval is 300 milliseconds.
Views

Predefined user roles
network-admin
Parameters
resend max-count: Specifies the maximum number of retransmissions for an EAPOL-Key packet, in the range of 0 to 3.
interval interval: Specifies the retransmission interval in the range of 200 to 500 milliseconds.
Usage guidelines
In Robust Security Network Association (RSNA) authentication, an AP and a client use EAPOL-Key packets in the four-way handshake to negotiate the keys. After that, the AP and the client periodically exchange EAPOL-Key packets to update the keys.
During key negotiation or update, the AP keeps retransmitting an EAPOL-Key packet until a response is received or the maximum number of retries for an EAPOL-Key packet is reached.
The system starts to count the retries when the maximum number of retransmissions is reached.
To ensure successful RSN key negotiation or update, you can increase the maximum number of retransmissions and the maximum number of retries for an EAPOL-Key packet.
For more information about RSN key negotiation or update, see "Configuring WLAN security."
Examples
# In service template view, set the maximum number of retransmissions for an EAPOL-Key packet to one and the retransmission interval to 400 milliseconds.

Parameters
cir cir: Specifies the CIR for packets destined to radios on other APs, in the range of 1 to 1300000 Kbps.
Usage guidelines
After you enable the scanning service (such as wireless probing, WLAN location, and WIPS) for an AP, a radio on the AP might receive packets destined to radios on a different AP than the radio. Such packets will increase the CPU usage and decrease the processing efficiency for packets destined to radios on the AP.
To address this issue, configure this command to set a rate limit for packets destined to radios on other APs.
Examples
# Set the CIR to 8 Kbps for packets destined to radios on other APs.

Parameters
count count: Specifies the maximum number of ARP requests that the AP can reply to on behalf of the gateway in a reply period. The value range for the count argument is 1 to 4096, and the default value is 10.
Usage guidelines
Perform this task to enable the AP to reply to ARP requests of clients on behalf of the gateway. If the MAC address of the gateway changes during a reply period, ARP failures might occur. To resolve this issue, you can specify a limit for the number of ARP requests that the AP can reply to on behalf of the gateway in a reply period. When the number of ARP requests that the AP has replied to reaches the limit, the AP will forward an ARP request to the gateway and perform either of the following tasks:
· If the gateway replies to the ARP request, the AP starts a new reply period with the new MAC address of the gateway.
· If the gateway does not reply to the ARP request, the AP starts a new reply period with the original MAC address of the gateway.
As a best practice to reduce the gateway's service load, enable this feature when the gateway's service load is heavy or the network condition is poor.

To quickly determine whether clients are online and save radio resources, execute this command to set the maximum number of keepalive packets that an AP can send to a client. The AP logs off a client if it does not receive any replies from the client after sending the specified number of keepalive packets to the client.
This command is mainly used in scenarios with high client mobility. If the network quality is poor, reduce the maximum number of keepalive packets that an AP can send to a client. As a best practice, use the default setting in scenarios with stable clients.
The configuration in radio view takes precedence over the configuration in an AP group's radio view.
Examples
# Enable client fast keepalive for AP ap1 and set the maximum number of keepalive packets to 300.
<Sysname> system-view
[Sysname] wlan ap ap1 model WA6320
[Sysname-wlan-ap-ap1] radio 1
[Sysname-wlan-ap-ap1-radio-1] rrop client fast-keep-alive enable count 300
# Enable client fast keepalive for APs with model WA6320 in AP group group1 and set the maximum number of keepalive packets to 300.
<Sysname> system-view
[Sysname] wlan ap-group 1
[Sysname-wlan-ap-group-1] ap-model WA6320
[Sysname-wlan-ap-group-1-ap-model-WA6320] radio 1

Parameters
port-num-list: Specifies a list of up to 10 TCP ports. The port number range is 1 to 65535.
dscp value: Specifies a DSCP value in the range of 0 to 63.
all: Deletes all the DSCP values specified for TCP packets.
Usage guidelines
A greater DSCP value represents a higher packet priority.
This command takes effect only on downstream packets.
If you execute this command with the same DSCP value multiple times, you can specify the DSCP value for up to 10 TCP ports.
If you execute this command with different DSCP values multiple times, the most recent configuration takes effect.
Examples
# Configure AP ap1 to use 50 as the DSCP value for TCP packets with port numbers 8001 and 8002.
<Sysname> system-view
[Sysname] wlan ap ap1 model WA6320
[Sysname-wlan-ap-ap1] rrop traffic-policy priority tcp 8001 8002 dscp 50
# Configure APs in AP group 1 to use 50 as the DSCP value for TCP packets with port numbers 8001 and 8002.

rrop ul-arp attack-suppression enable
Use rrop ul-arp attack-suppression enable to enable upstream ARP packet suppression.
Use undo rrop ul-arp attack-suppression enable to disable upstream ARP packet suppression.
Syntax
rrop ul-arp attack-suppression enable [ threshold threshold-value ] [ block-time time ]
undo rrop ul-arp attack-suppression enable
Default
Upstream ARP packet suppression is disabled.
Views
System view
Predefined user roles
network-admin
Parameters
threshold threshold-value: Specifies the threshold for triggering upstream ARP packet suppression. If the number of ARP packets that an AP receives from a client in one second reaches the threshold, the AP discards all ARP packets from the client within the specified suppression period. The value range for the threshold-value argument is 2 to 4096, and the default value is 10.
block-time time: Specify the upstream ARP packet suppression period in the range of 10 to 6000 seconds. The default suppression period is 60 seconds.
Usage guidelines
Execute this command to protect APs against ARP flooding attacks. If the number of ARP packets that a client sends to an AP in one second reaches the specified threshold, the AP discards all ARP packets from the client within the specified time period.
This command does not take effect on ARP requests for the gateway.
Examples
# Enable upstream ARP packet suppression.

sacp roam-optimize traffic-hold enable
Use sacp roam-optimize traffic-hold enable to enable data transmission holding during roaming.
Use undo sacp roam-optimize traffic-hold enable to disable data transmission holding during roaming.
Syntax
sacp roam-optimize traffic-hold enable
undo sacp roam-optimize traffic-hold enable
Default
Data transmission holding during roaming is disabled.
Views
Service template view
Predefined user roles
network-admin
Usage guidelines
With data transmission holding during roaming enabled, the device caches the packets during client roaming and sends the packets to the client after the client roams successfully to reduce the packet loss during client roaming. With data transmission holding during roaming disabled, the device ages out the cached packets after a period of time and will not send the packets to the client. As a best practice, enable this feature in a scenario that is sensitive to packet loss.
To make this feature take effect, enable client association at the AC and enable the AC to forward client data traffic.
This feature is not supported in an AC hierarchy network or inter-AC roaming network.
Examples
# Enable data transmission holding during roaming.
<Sysname> system-view
[Sysname] wlan service-template 1
